## About
The first collection in the Derp Birds universe, the Derp Birds and PREDs are considered the main characters of the story and project. Once [Derp Birds: Rebirth(2.0)](/derp-birds/more/roadmaps/season-3/derp-birds-2.0-rebirth.md) launches, this collection is now considered legacy, and their primary use will be to swap for the upgraded to [The Derp Birds](/derp-birds/characters/main-collections/the-derp-birds.md) collection.
Each Derp Bird has 7 unique traits: Head, Ears, Beak, Eyes, Body, Back, and Tail as well as a background trait. Each trait(except for the background) comes from one of the 14 archetypes. Some archetypes are rarer than others.
The 14 Archetypes
* Dave
* Astro
* Magician
* Ninja
* Redneck
* Stoner
* DJ
* Viking
* Monk
* Corpo
* Cyborg
* Buff
* Mad Scientist
* Deity
Derp Birds with all traits of a single archetype are called Perfect Specimens and have a unique background. Perfect Specimens earn more from staking rewards than other Birds.
All Derp Birds fall into 1 of 7 rarity ranks: Common, Uncommon, Scare, Rare, Epic, Mystical, and Legendary.
## Utility
* Can be staked to earn $DERP
* Primary utility: use Legacy Derp Birds to upgrade to the 2.0 collection: [The Derp Birds](/derp-birds/characters/main-collections/the-derp-birds.md)
* Each Derp Bird adds +10 additional partner staking slots to the holder's account
* One Derp Bird is needed to unlock partner staking for an account– without a Derp Bird, a user cannot earn staking rewards for partner NFTs

`ask` is the immediate question: it should be specific, self-contained, and written in natural language.
`goal` is optional and describes the broader end goal you are ultimately trying to accomplish on behalf of the user. GitBook uses it to tailor the answer towards what is most useful for that goal.
